Dolomite:

" Dolomite " is a word that is used by geologists in two different ways: 1) as the name of the mineral dolomite ; and, 2) as the name of a rock known as dolomite , dolostone, or dolomite rock. Dolomite rock is defined as sedimentary carbonate rock composed of more than 50% mineral dolomite . Dolomite is characterized by its nearly ideal 1:1 stoichiometric ratio of magnesium to calcium. It is distinct from high-magnesium limestone in that the magnesium and calcium form ordered layers within the individual dolomite mineral grains, rather than being arranged at random, as they are in high-magnesium calcite grains. [13] In natural dolomite , magnesium is typically between 44 and 50 ... Dolomite is a calcium magnesium carbonate mineral and a rock-forming mineral that forms through dolomitization of limestone. Learn about its crystal structure, physical and optical properties, geological importance, and applications in industry and construction. The name dolomite has been given in honour of the French chemist, Dolomieu (1750-1801). Dolomite is an important natural resources used in many industries. It occurs as a rock and shows valuable composition, being a mixture of lime and magnesia.
